KOOTION 10 Pack 32GB Flash Drive USB 3.0 Thumb Drive USB Drives Jump Drives Keychain Memory Stick Black

I ordered 2 boxes of 10 just over a year ago. Every single one was excellent! No bad ones, very reliable, steady transfer speeds, burst data rate is really good, large data transfer is very good, Multipleto large amounts of small data file transfers is little to be more desired but not unreasonable for the cost per drive. I used many for Windows 10 installation flash drives and gave to computer sale clients, gave to clients for quick data transfers. I just order my third set of 10 and will use this next set for some macOS install Flash drives. I will continue to buy this product over and over. I actually leave one in my back pocket and sit on it all the time, this thing has not been crushed by my fat A**, lol. Still works today!

Summary: good drives for the price; decent transfer speeds. Details: Main desktop computer is a Dell XPS 8920. System drive is a 250GB SSD. Two other HDDs for data, 1.0TB and 6.0TB. External USB connections are: USB-C 3.1 (rear), USB-A 3.1 (rear), USB-A 3.0 (front). THe transfer speed difference between the front (3.0) and back (3.1) was negligible. Test Method: The test program I use is ATTO Disk Benchmark (freeware). I tried a few different ones, and settled on this one because the result picture was relatively easy to compare to other results. When evaluating results, I mainly looked at the transfer speeds for files size 1 MB or larger. Pros: good price point; good fit & finish; bright activity LED; decent transfer speed. Cons: None. Recommendations: If you buy a pack of 10, remember to test them all in case any are dead on arrival (all mine were good).

So far, so good .... have had for two months and used four of the ten without problems. It is getting harder to find 1GB USB drives for a fair price - but they are perfect for music for plugging into my vehicle or just attach to my computer to hear certain genre ... 1GB is the perfect size. Easy to use and simply to open and close - just slide the sleeve around the USB. The speed of transfer is NOT fast - but acceptable. I haven't had any problem with the cover coming free or detaching (someone apparently did). The sleeve is blank and easy to write on. It had no logo on either side (like the picture demonstrated). I also use them for transferring multiple pdfs and docx files of active projects as well as for transferring files between machines. Although limited to 1 GB (by choice), they do the job and work well for transporting files.

They work

I have purchased the 16gb 50 packs six times now as I use these for my legacy video conversion business. Out of 300 drives, I have had 1 not work, which is really amazing. This is my go to brand!

Great for transferring movies and archival memories. 32 GB more than enoughfor my purposes, but I figure I can always format them again. I use a small point Sharpie for description of contents. Quite durable and outlasting me.

We go through these quickly at work. Have not had any trouble transferring data to or from.

At this price I really didn't expect quality from a 10pack of USB 3.0 drives. I expected a few to be defective and poor performance on the rest. However, every single drive passed a badblocks write test with no errors at all. Running basic benchmark showed what I would consider very usable performance. Benchmark numbers can vary wildly based on on setting but this was a favorable comparison to the more expensive drives I had on hand. Assuming they don't degrade later I'm pleasantly surprised.
